Referring to FIG. 7, FIG. 7 illustrates a flow chart of the step S22 of a method of pairing a computer and a wireless electronic device according to the first embodiment of the present invention.
In the step S220, the wireless mouse 40 is switched into the pairing mode to generate and transmit a set of random number.
In the step S221, the wireless mouse 40 generates an initialization code by using the random number generated by itself and the request response message in the step S20 to provide an encrypted environment for verification.
In the step S222, the computer 30 switches into the pairing mode and receives the set of random number.
In the step S223, the computer 30 generates an initialization code by using the random number from the wireless mouse 40 and the request response message in the step S20 to provide an encrypted environment for verification.
In the step S224, a verification of the computer 30 is processed. The computer 30 generates a set of verification random number and transmits the verification random number to the wireless mouse 40. The wireless mouse 40 computes the verification random number by using a verification function to generate a response number, and then compiles the response number to the computer 30 to generate a first pairing data. If the response number and the number computed by the computer 30 are the same, then the first pairing data is success, however, if they are different, then the first pairing data is failure.
In the step S225, an inverse verification of the wireless mouse 40 is processed. The wireless mouse 40 generates a set of inverse verification random number and transmits the inverse verification random number to the computer 30. The computer 30 computes the inverse verification random number by using an inverse verification function to generate another response number, and then compiles the other response number to the wireless mouse 40 to generate a second pairing data. If the other response number and the number computed by the wireless mouse 40 are the same, then the second pairing data is success, however, if they are different, then the second pairing data is failure.
After the first pairing data and the second pairing data are generated, the step S226 is processed to interchange the first pairing data and the second pairing data. After the computer 30 transmits the first pairing data to the wireless mouse 40 and receives the second pairing data from the wireless mouse 40, the step S227 is processed to determine whether the first pairing data and the second pairing date are both success or not. If yes, then the computer 30 and the wireless mouse 40 are success in pairing and then the step S23 is processed. If not, then they are failure to be paired.
Referring to FIG. 5 again, in the step S23, the computer 30 generates a pairing complete message 32, which is displayed on the monitor 31 of the computer 30 for notifying users that the computer 30 and the wireless mouse 40 are success in pairing. Moreover, the computer 30 may further transmits a pairing notice signal to the wireless mouse 40 to let the wireless mouse 40 generate a light signal, a sound signal or a vibration signal, so as to notify users where is the paired wireless electronic device 40.
Referring to FIG. 8, FIG. 8 illustrates a schematic view of a method of pairing a computer and wireless electronic devices according to a second embodiment of the present invention. A computer 50, a monitor 51 and two wireless mice 61, 62 are presented in FIG. 8. First, a power source of the wireless mouse 61 is activated and a pairing button (not shown) of the wireless mouse 61 is pressed to let the wireless mouse 61 generate and transmit a pairing request message, wherein the pairing request message contains a media access control (MAC) address of the wireless mouse 61.
Referring to FIG. 9, FIG. 9 illustrates a flow chart of a method of pairing a computer and wireless electronic devices according to the second embodiment of the present invention. In the step S30, the computer 50 starts to search wireless electronic devices adjacent to the computer 50, wherein the wireless electronic devices in the present embodiment comprise the wireless mouse 61 and the wireless mouse 62. The wireless mouse 61 and the wireless mouse 62 have different MAC addresses.
Referring to FIG. 10 for the searching process, FIG. 10 illustrates a flow chart of the step S30 of a method of pairing a computer and wireless electronic devices according to the second embodiment of the present invention. In the step S301, the computer 50 with wireless transmission function receives the pairing request messages transmitted by the wireless mouse 61 and the wireless mouse 62, and processes the step S302 in a predetermined period to determine whether the computer 50 receives at least one pairing request message or not. If yes, then process the step S303 to transmit request response messages to the wireless mouse 61 and the wireless mouse 62 according to the pairing request messages and go to the step S31. If not, then the searching process is failure. The wireless mouse 61 and the wireless mouse 62 switch into a pairing mode when the wireless mouse 61 and the wireless mouse 62 receive the request response messages.
In the step S31, the computer 50 obtains and records the MAC addresses of the wireless mouse 61 and the wireless mouse 62 by the pairing request messages in the step S30. Since the wireless mouse 61 and the wireless mouse 62 have different MAC addresses, the computer 50 may recognize the wireless mouse 61 and the wireless mouse 62 by the MAC address records.
In the step S32, the computer 50 is pairing with one of the wireless mouse 61 and the wireless mouse 62. For example, the computer 50 is pairing with the wireless mouse 61, wherein the pairing process is similar to the conventional pairing process and simply described in the following description. Referring to FIG. 11, FIG. 11 illustrates a flow chart of the step S32 of a method of pairing a computer and wireless electronic devices according to the second embodiment of the present invention.
In the step S320, the wireless mouse 61 is switched into the pairing mode to generate and transmit a set of random number.
In the step S321, the wireless mouse 61 generates an initialization code by using the random number generated by itself and the request response message in the step S30 to provide an encrypted environment for verification.
In the step S322, the computer 50 switches into the pairing mode and receives the set of random number generated by the wireless mouse 61.
In the step S323, the computer 50 generates an initialization code by using the random number from the wireless mouse 61 and the request response message in the step S30 to provide an encrypted environment for verification.
In the step S324, a verification of the computer 50 is processed. The computer 50 generates a set of verification random number and transmits the verification random number to the wireless mouse 61. The wireless mouse 61 computes the verification random number by using a verification function to generate a response number, and then compiles the response number to the computer 50 to generate a first pairing data. If the response number and the number computed by the computer 50 are the same, then the first pairing data is success, however, if they are different, then the first pairing data is failure.
In the step S325, an inverse verification of the wireless mouse 61 is processed. The wireless mouse 61 generates a set of inverse verification random number and transmits the inverse verification random number to the computer 50. The computer 50 computes the inverse verification random number by using an inverse verification function to generate another response number, and then compiles the other response number to the wireless mouse 61 to generate a second pairing data. If the other response number and the number computed by the wireless mouse 61 are the same, then the second pairing data is success, however, if they are different, then the second pairing data is failure.
After the first pairing data and the second pairing data are generated, the step S326 is processed to interchange the first pairing data and the second pairing data. After the computer 50 transmits the first pairing data to the wireless mouse 61 and receives the second pairing data from the wireless mouse 61, the step S327 is processed to determine whether the first pairing data and the second pairing date are both success or not. If yes, then the computer 50 and the wireless mouse 61 are success in pairing and then the step S33 is processed. If not, then they are failure to pair.
In the step S33, the computer 50 generates a pairing complete message 52, which is displayed on the monitor 51 of the computer 50 for notifying users that the computer 50 and the wireless mouse 61 are success in pairing. Moreover, the computer 50 may further transmits a pairing notice signal to the wireless mouse 61 to let the wireless mouse 61 generate a light signal, a sound signal or a vibration signal, so as to notify users where is the paired wireless mouse 61.
Further, the pairing complete message 52 further comprises a pairing confirming message, which is displayed as “Is the paired wireless electronic device is correct?”, and thus users may confirm whether the wireless mouse 61 is the correct pairing subject or not; if yes, then a re-pairing request message will not be generated; however, if not, then a re-pairing request message is generated.
In the step S34, the computer 50 determines whether a re-pairing request message is received or not. If the wireless mouse 61 is the wireless electronic device desired to be paired, then users may click a button 53 marked as “Yes and complete.” to complete the pairing process, and then the wireless mouse 61 may be normally operated on the computer 50. If the wireless mouse 61 is not the wireless electronic device desired to be paired, then users may click a button 54 marked as “No and re-pairing.” to transmit a re-pairing request message to the computer 50 and go to the step S35. In the step S35, the computer 50 confirms the MAC address records, excludes the MAC address record of the wireless mouse 61, and then reads the MAC address record of the wireless mouse 62. Thereafter, the step S32 is processed to pair the computer 50 and the second wireless electronic device 62.
According to the description of the above-mentioned preferred embodiments, it is obvious that the method of pairing a computer and at least one wireless electronic device of the present invention uses the step of recording the MAC address(s) of the wireless electronic device(s) to replace the step of selecting a correct wireless electronic device from a searching list in the conventional method. Therefore, the present invention may not only save lots of time for selection, but also provide a simple pairing method to avoid difficult selection from several wireless electronic devices belong to the same type that comes out at the same time that result in quite difficult to use and inconvenient.
